JOHN J'. DANBERG, OF BEACH, NORTH DAKOTA, ASSIGNOR OF ONE-HALF '10 JOHNPIERZINA, OF BEACH, NORTH DAKOTA.

HOSE-COUPLING.

To all whom it may concern:

Be it known that I, JOHN J. DANBERG, a citizen of the United States,residing at Beach, in the county of Billings and State of North Dakota,have invented certain new and useful Improvements in Hose-Couplings, ofwhich the following is a specification, reference being had to theaccompanying drawings.

This invention relates to new and useful improvements in hose-couplings,the object of the invention bein to provide an effective and inexpensiveevice for readily connecting and disconnecting sections of a pipe orhose.

Another object of the invention is to provide a detachable hose couplingwhich will possess advantages in points of efliciency and durability, isinexpensive of manufacture and at the same time is simple inconstruction and operation. With the above and other objects in view theinvention consists in the novel features of construction and thecombination and arrangement of parts hereinafter more fully described,pointed out in the claim, and shown in the accompanying drawings inwhlch,

Figure 1 is a side elevation of my improved coupling. Fig. 2 is alongitudinal sectional View. Fig. 3 is a transverse sectional view onthe line 33 of Fig. 1, and Fig. 4 is a similar view on the line 4-4 ofFi 1.

ReFerring more particularly to the drawings, 1 indicates the femalemember which comprises an externally-corrugated ipe 1,

rovided with an enlarged portion 2 ormed intermediate of its len h. Theenlarged portion 2 is provided with a circular chamber 3 in which isdisposed the reduced end 4 of the member 1, a shoulder 5 being formed atthe inner end of the chamber 3 and: adapted to encircle the inner end ofthe reduced portion 4. Arranged within the chamber 3, encircling thereduced portion 4 and resting upon the shoulder 5 is a coil spring 6.The reduced portion 4 is formed with a continuous smooth anduninterrupted exterior surface and extends half its length beyond theouter end of the enlarged portion 2 and is provided with a reduced end 7adapted to form an annular shoulder 8. Mounted upon the reduced end 7and resting on the shoulder 8 is a rubber washer 9 which is adapted tofrictionally Specification of Letters Patent. Application filed April20, 1912. Serial No. 692,091.

.engage with the inner walls of the male coupling member 10 to preventwater or other liquids from entering the chamber 3. Formed integral withthe outer. end of the enlarged portion 2 and projecting outwardly inalinement therewith are the arms 11 which are arranged in spacedrelation and are laterally extended at their outer ends and returnedupon themselves for a short distance to form rearwardly facing hookmembers 12' adapted to engage with the equidistant pins 13 formed uponthe outer periphery of the male coupling member. Arranged between theinner end of the male coupling 10 and the spring 6 is a washer 14 whichmay be of rubber or other suitable elastic material to prevent theleakage of any Water which might enter the chamber 3. The male couplingmember 10 is provided with a corr-u ated portion 15 to which is securedone of t e hose'sections.

From the above it will be seen .that I have shown and described thecoupling adapted for use in connecting two sections of hose but it willbe understood that the coupling can be readily modified so that twosections of pipe or other tubular members can be connected together bythe use of my improved coupling.

From the above description taken in connection with the drawings theutility and operation of the coupling will be readily understood. Inconnecting two sections of hose the male member 10 is first engaged withthe reduced portion of the pipe 1, the member is then pushed inwardlyinto the chamber 3 and at the same time compressing the spring 6. Themale member 10 is pushed inwardly until the pins 13 will engage beneaththe hook members 12 by the partial rotation of the member 10. TheWashers 9 and 13 will insure a water tight connection and it will bereadily a parent that the coupling members may quic y and easily beconnected and disconnected.

What I claim is:

A hose coupling comprisin mating members, one of which is forme with anenlarged portion and a reduced portion within the enlarged portion andextending beyond the latter, the exterior of the saidvreduced portionbeing entirely smooth and uninterrupted throughout its length and theenlar ed portion being formed with a plurahty of integral longitudinallyprojecting between the said reduced portion and the enlarged ortionofthe first named member and bearing against said washer, for the purposespecified.

In testimony whereof I hereunto affix my signature in the presence oftwo witnesses.
